Question

我正在研究触发器/测试类，我无法弄清楚如何使测试类工作。我知道我需要更新我使用触发器的机会，但我不知道如何以及如何验证我的触发器是否正常工作。

触发：

trigger add_primary_advisor on Opportunity(before update) {
for(Opportunity o: Trigger.new){    

     if (o.IsClosed && !Trigger.oldMap.get(o.id).IsClosed) {
       OpportunityContactRole contactRole =
            [select ContactID from OpportunityContactRole where IsPrimary = true and OpportunityId = :o.id];
       if (contactRole != null) {
         o.Primary_Advisor__c=contactRole.ContactID;
       }
     }
   }    
}

测试类：

@isTest
private class primary_advisor_test {
    static testMethod void primary_advisor(){
    Opportunity opp = new Opportunity(Name='test opp', StageName='stage', Probability = 95, CloseDate=system.today());
    insert opp;


update opp; 

}

}

Answer 1

问题是你在调用update之前没有更改任何字段试试这个

opp.Probability  = 90;
update opp;

Answer 2

在进入测试类的解决方案之前，我想指出触发器没有建立，因为你在循环中有一个SOQL查询，这不是最佳实践。

我不知道opportunityContactRole对象的确切功能，我只是假设它是一个对象，它将保存联系人ID和opportunityID，或多或少像一个联结对象。

@isTest
private class primary_advisor_test {
  static testMethod void primary_advisor(){
  //Create a contact that will be added to the opportunityCOntactRole.
  contact con = new contact(name='testCon');// add all the required field as per your org settings
  insert Con;
  Opportunity opp = new Opportunity(Name='test opp', StageName='stage', Probability = 95, CloseDate=system.today());
  insert opp;
  //Create the opporunityContactRole.
  opportunityCOntactRole oppCOn = new new opportunityCOntactRole(OpportunityId=opp.id, contactId= con.Id, isPrimary=true);
   insert oppCon;
   //update the opportunity so that it is closed and enters the if conditon in your trigger.
   opp.stageName='Closed';


   update opp; 

  }
}
